According to NFPA, what is the maximum allowable shaft seal pressure?

The maximum allowable shaft seal pressure, according to the National Fire Protection Association (NFPA) standards, is set at 3 PSI. This specification is important for ensuring that equipment operates safely and efficiently. A pressure limit of 3 PSI helps prevent excessive leakage and potential mechanical failures, which could lead to safety hazards. Operating within this limit helps maintain the integrity of the equipment and reduces the risk of fire or explosion due to the leakage of flammable fluids.

This standard is crucial for professionals in the oil fuel industry as it provides clear guidelines for the installation and maintenance of equipment, promoting safety and performance. Understanding and adhering to these limits is essential for compliance with regulations and ensuring the longevity of the systems in use.
